NEERNAL-CMBUSTIO MOTOR. .AND VAITLE THEREFB.

* application met march 2, 191s. serial matassa y To all whom #may concern Be it known that, l, FRANK G. Fernse, a

, citizen' of the United States, residing at 111 Woodlawn ave., Aldan, in the county of Delaware and State (if-Pennsylvania, have invented new and us'iul Improvements in internal-Combustion Motors and Valves Therefor, of which the following is a speciication.

The-invention relates to internal combus tion motors, and has for an object to provide a novel form of internal combustion motor and valve therefor, to result in simplicity of operation, ready removal of any of the valve parts for the purpose of cleaning or grinding; proper registration of the various f ports, associating themotcr body with the valve as to the admission and exhaustion of gases, and therefore the eiective operation of a motor of the character that will be described.

Among other features, the invention comprehends a valve structure which is of a unitary construction, in that the valve proper can beremoved in its entirety for the purpose-of grinding or cleaning, and in its entirety can be adjusted in its casing or sleeve, so as to bring about proper'registration of the various-port openings.

Further the invention comprehends a motor and valve which can be so arranged with respect to the usual timin mechanism, that therewill be no chance o' disarrangement of the timing mechanism relative to the motor proper and the valve, as to the` explosion of the gases in the cylinders.

ln the further disclosure o the invention, reference is to be had to the accompanying drawings, constituting a part of this' specification, and in which similar characters of reference denote corresponding parts in all the views, and in Which- .y

` liigfY is a diagrammatic Iview showingy the cylinders of the motor; and the respective positions'of the parts of the valveto disclose the cycle of operation of the motor. Referring more particularly to the views, the numeral 10 indicates the motor in its entirety, and which comprises the usual block 1.1 formed to'provide cylinders 12 12-12band123 with corresponding pistons 1.? -13- -13b and 132 respectively. bloclr 1.1 may be suitably Water-jacketed by providing a water-jacket 14, and the pistons 13---131--13b and 13c .respectively are con nected to connectin rods 15--151-15b and 15, the latter havln With a' crank shaft 16, )ournaled in the usual crank case 17 of the motor. y s

The upper part of the block 11 is formed to provide a casing 18, in which are formed ports 19-19"-19h and'19,c which may be more particularlytermed cylinder ports, to differentiate from other ports hereinafter more fully described. The 'casing 18 has va chamber 20 suitably tapered and in which is arranged a sleeve 21, the sleeve being tapered and secured rigidlyl in they casing by a driving fit. form, indicated by the numeral 22, may be secured in the casing l18 to supply oil, which The suitable connection An oil cup of any desired e operating along a channel 23 in the sleeve, f

let| openings. The sleeve 21 is further 'provided With openings 29--29-29" and 29 which communicate directly with respective cylinder ports 19-4191--19b and 19, shown in Fig. 1.

Threaded in one end of the casing 18 is a plug 30 which carries a screw 31, and dis- Aposedvvithin the sleeve 21 is a valve 32 of a tapered formation to the sleeve, with one end of the valve abutting against the inner end'oi' the adjusting screw 31, the

other end of the valve carrying a shaft 33 eXtendin",r extcriorly of the casing, on which 1s secured a suitable toothed win-.el 254i-, which muy he in the nature or a sprocket VWheel or otherwise, constituting a'drlvmg member that may have vsuitable connection by a; chain driving crank shaft 14.

"The valve 32, as mentioned heretofore, is tapered to fit perfectly Within the sleeve,

and a series of compression Washers or other e]en'1ents 37 are placed against the enlarged end of the valve, with siiitahle plug 3S threaded in the casing 1S, and orn'iing a bearing for the Valve shaft 33, vns clearly shown in Figs. l and 2.

` The valve 32 is formed with aseries of gouged-out recesses or ports, which I may terni valve ports, and Which I indicate by the numerals 3535*39a 39 and 39e, the valve ports being arranged in Whet )night be termed a staggered position upon the valve as to its periphery, so that in the rotation of the valve Within the slee-Ve, these ports will be brought into or ont of registration or cormnnnication with the sleeve openings Q-QQQa-Q" and 25, QT--QT-IZTF and 27, 29'-29-29" and :29", and therefore into end out of registration with the respective cylin-v der ports 9--19a-19" and 19.

From what hasbeen described of the valve and the encirciing Valve sleeve, it Wiiibe clear that a .desirable relation between the valve ports and the sieeve openings or ports can heeasily obtained in the assembling of the two structures, hy associating the valve and sleeve prior to their connection or relation with the .motor itseii, andnyhereby the yports of the Vaive can be easily marked thereon through the openings of the sleeve,

and the ports then gouged out or izirodueedr in the desired manner.

Referring new to Fig'. it `will he seen that with the Valve and `sleeve arranged with respect to the cylinder ports sind motor body, the desired operationnfiil take plateel as shown in Fig; 7, Where, :tor instance, when the piston 13 is assuming a downward stroke to snel; in to the. cylinder '12 a'quantity of Vapor or gas, the particular port 3Q of the valve will he in position to providethe/desired passage from the inlet 26 mto'the portl 89, and through the port 25 or' the sleeve to the cyhnder port 19, so that a coinpiete open passage will he iorined, whereby tns ges can be readily taken in, and vwill .be

sucked in with the downward movement of the piston 1 3. At this time, the second piston 13ft will he on en upward stroke to com press gas that has heen already received lin its particular cylinder 12a, and' atthis time the valve heilig in position to permit. of gas being sucked into the rst cylinder 19.,.wi11 heclosed 'as to the v second cylinder, hy reason deposits, or for grinding down or trningup lthe openings in the 'Itwill of course be nnderstood that do not limit inyse'lf to the partieniar disclosure incenso will be in position to provide a passage `from the cylinder 12b, hy reeson'oic the cylinder port 19 being'in direct registration with the port 29 of the sleeve, the port 39h of the valve andthe exhaiist port And 'so also thefourthcylinder12, having its piston in uppermost .position tio come down et the point of compression and compress the gas inthecyiinder, the cylinder. port 19C will be closed by reason of the valve 32, as shown in Figi.

From the4 foregoing it will` thiis he seen vthat regardless of the particular arrange ment' ofthe cylinders, their ports end'the f sleeve ports with respect to the Valve and itsV ports, the cycle or" operation will be such that the various parts will cooperate to lering about the taking-in of gas in one cylinder, While another is under compression, a third on exhaust and a fourth on compression, and with this arrangement in mind, it will he seen thatv hy having the Valveshaft in direct association with suitable timing,r mechanism 40, the explosion of themixtnre in aperticular cylinder of the I notor, Wiii' be accomplished et the time when its piston has reached the proper position in said cyl inder, and the Valveportto that cylinder is closed. 'v

Vith the construction set forth it wili seen that one of the aims-is to provide e clear passage from they intake 'manifold to the Avarious registering ports of the sleeve, the valve and the cylinder, when a' particu- .lar cylinder and its piston are prepared to receive the mixture, 'and so also on thevcoinh position ot the ice pression, exhaust and combustion, it will be' 5 l seen that in exhausting the burnt gas, the

y'saine will pass out through the exhaust port 28, e free passage being provided therefor. y By having the velve'32 provided with en integral Valve shaft a direct rotating;` connection can be secured through 'the .nie-- diurn ofthe connection with the crank shaft, whether it he by gear or chain, or otherwise,

Vand that in this arrangement a positive connection is ai'so secured with the timing inech- ',anism soas to greatly simplify this part of thenoperation endprocedure, and it xviii he clear that withv very littletrouhie, the valve 4 n canbe removed and the cylinder also, it desired, or theupurpose ofrernovingcerhon the vaive, sleeve;r
